Roland HP-201 用户手册

 

If you think there’s a problem, read this first.

 

Is the power cord connected and plugged in 
correctly? (p. 12)

 

Is the panel locked? (p. 35)
Turn the power off, then back on.

 

Is the volume level of the HP201 turned all the 
way down? (p. 14)

Are headphones plugged in? (p. 13)
Has a plug remained connected to the Phones 
jack?
Plugging headphones or other plugs into the 
headphone jack stops sounds from playing 
through the speakers.

Is Local Off selected? 
When Local Control is set to Off, no sound is 
produced by playing the keyboard. Set Local 
Control to “On” (p. 39).

Is V-LINK switched on?
While V-LINK is switched on, no sound is 
produced when you press any of the twelve 
keys at the left end of the keyboard (p. 35).

 

Have all devices been switched on?

Are the MIDI cables connected correctly?

Does the MIDI channel match the connected 
instrument? (p. 38)

 

When the HP201 is connected to an external 
sequencer, set it to the Local OFF mode 
(p. 39). 
Alternatively, the sequencer could be set so its 
MIDI Thru feature is OFF.

 

Is the panel locked? (p. 35)
Turn the power off, then back on.

 

The maximum number of notes that the 
HP201 can play simultaneously is 128. 
Frequent use of the damper pedal when 
playing along with a song may result in 
performance data with too many notes, 
causing some notes to drop out.

 

Are the settings for the “Temperament” (p. 33) 
and “Stretch Tuning” (p. 34) correct?

Is the setting for the “Master Tuning” correct? 
(p. 32)

 

Is the pedal connected correctly? 
Make sure the pedal cord is securely 
connected to the pedal jack on the bottom of 
the unit, at the rear (p. 12).

 

Adjust the adjuster underneath the pedal so 
that the adjuster presses firmly against the 
floor surface (p. 14).

 

On an acoustic piano, notes in the upper one 
and a half octaves of the keyboard continue 
to sound until they decay naturally, regardless 
of the damper pedal. There is a difference in 
the timbre as well. Roland pianos faithfully 
simulate such characteristics of the acoustic 
piano. On the HP201, the range that is 
unaffected by the damper pedal will change 
depending on the Transpose setting.

 

When listening through headphones: 

Some of the more flamboyant and 
effervescent piano tones feature an ample 
high-end component, which may make 
the sound appear to have metallic 
reverberation added. Since this 
reverberation becomes particularly 
audible when supplemented by heavy 
reverb, you may be able to diminish the 
problem by reducing the amount of 
reverb applied to the sound.

When listening through speakers: 

Here, a different cause (such as 
resonance produced by the HP201) 
would be suspect. Consult your Roland 
dealer or nearest Roland Service Center.

 

When listening through speakers: 

Playing at loud volumes may cause 
instruments near the HP201 to resonate.
Resonation can also occur with 
fluorescent light tubes, glass doors, and 
other objects. In particular, this problem 
occurs more easily when the bass 
component is increased, and when the 
sound is played at higher volumes. Use 
the following measures to suppress such 
resonance. 
• Place speakers so they are 10–15 cm 

from walls and other surfaces. 

• Reduce the volume. 
• Move the speakers away from any 

resonating objects. 

When listening through headphones: 

Here, a different cause would be suspect. 
Consult your Roland dealer or nearest 
Roland Service Center.

 

Could you be using a connection cable that 
contains a resistor? 
Use a connection cable that does not contain 
a resistor.
